I would like to have additional information about your system configuration. Please run the following utility and attach the results.

Thank you for the report.
I am currently testing same hardware configuration with the latest graphics drivers version 4901,
I need to know if this problem happens when running dual screen in Clone mode or Extended mode.
Thank you for your time.
Thank you for your patience.
I finished this lab today, I did not get same symptoms. When I tested the Intel® NUC with latest graphics drivers and BIOS I was able to open Word, Excel, and Outlook without issues.
If you have the chance to test different video adapter as the one I tried below:

Thanks for that Allan, moving one of our clients from the USB-C to VGA adaptor to the HDMI output (this client is only using one monitor) seems to have no issues. It sounds like it may be a bug between the brand of adaptor we are using and the NUC's. We have tried replacing the adaptors and still the same issue. I will try and get hold of a different brand and will let you know how it goes.
Thanks for your help!
